HERMANN ADOLF RUETSCHI, OF PUEBLO, COLORADO.

MEAQURING AND DELIVERING MACHINE.

To all whom it may concern,

Be it known that I, HERMANN AnoLF RUn'r- SOHI, a citizen of the United States, and a resident of Pueblo, in the county of Pueblo and State of Colorado, have invented a new and Improved Measuring and Delivering Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved measuring and delivering machine, more especially designed for measuring and delivering loose materials, such as coal, grain, ore, rock and the like, and arranged to insure the free passage of the matcrial from a supply chute to a measuring receptacle.

In order to accomplish the desired result, use is made of a chute adapted to contain loose material to be measured and delivered, a fixed measuring receptacle having an inlet for receiving the material from the said supply chute and having an outlet for the measured material, and a double gate mounted to oscillate and controlling the said inlet and the said outlet to open the one when closing the other and vice versa. Use is also made of a receiving receptacle, such as an elevating bucket or the like, and mechanical means controlled by the said receiving receptacle and connected with the double gate to actuate the latter in unison with the ascent and descent of the receiving receptacle.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the measuring machine; Fig. 2 is an enlarged sectional side elevation of the supply chute, the measuring receptacle and its double gate, the latter being in position for filling the measuring receptacle; Fig. 3 is a similar view of the same with the double gate in position for discharging the loose material from the measuring receptacle; Fig. 4: is a plan view of the same; Fig. 5 is'an enlarged sectional plan view of one of the trunnions carried by one side of the measuring receptacle and on which the double gate is mounted to oscillate; Fig. 6 is a face view of: one of the bearings of the double gate; and Fig. 7 is a sectional side elevation of the measur Specification of Letters Patent.

ing and delivering machine and showing a with a chute B adapted to discharge into a measuring receptacle C of a predetermined size so that the amount of loose material measured and delivered by this receptacle at each operation can be readily determined. The measuring receptacle 0 is provided with an inclined bottom C, preferably parallel with and located a distance below the bottom of the supply chute B, and the said measuring receptacle 0 is further provided with sides C an open segmental upper end C and a lower end C having an outlet C reaching to the lower end of the bottom C, as will be readily understood by reference to Fig. 3. The upper portion of the open end C is in register with the segmental end of the chute B to form an inlet for the loose material to pass from the chute B into the measuring receptacle C.

The inlet C and the outlet C are controlled by a double gate having gates D and D, of which the gate D controls the inlet (1 while the gate D controls the outlet C the gates D and D being segmental and connected with each other outside of the sides C by connecting arms D provided at their middle with bosses D journaled 011 trunnions lil secured to the sides C of the measuring receptacle C, as plainly indicated in Fig. 5. Roller bearings E are preferably interposed between the trunnions E and the bosses D to insure an easy rocking or oscillating oi the double gate D, D. By reference to Figs. 2 and 3 it will be noticed that when the gate D is in open position the gate D is in closed position (see Fig. 2), and when an oscillating motion is given to the double gate, as shown in Fig. 3, then the gate D closes the inlet C to the chute l3 while the gate D opens the outlet C to allow the loose material to slide out of the measuring receptacle G. Thus the gate D cuts 01? the loose material from the chute 13 while the loose material contained in the measuring receptacle C is discharged through the opening C lVhen the double gate D, D is rocked back to the position shown in Fig. 2 then the outlet C is closed by the gate D while the upper portion of the inlet C is opened to allow the loose material to pass from the chute B to the measuring receptacle G to refill the same.

By constructing the measuring receptacle G in the manner described and locating the same relative to the chute B as set forth, it is evident that the receptacle C readily fills with the loose material at the time the gate D is opened and the gate D closed. By ar ranging the connecting arms D and the trunnions E on the outside of the measuring receptacle C no undesirable obstructions are formed inside of the measuring receptacle C, and the double gate D, D is free to oscillate.

It will be noticed that the gates D, D are subjected to pressure on one side only, and this pressure is reduced to a minimum when the gate D swings upward into closed position as it tends to roll the material forward due to its segmental travel, and the gate has only to contend with the pressure of the angle of repose of the material contained in the receptacle C. The pressure is also reduced when the gate D starts to ascend thereby causing the material to spread in the lower portion of the upper end of the receptacle 0 owing to the fact that the bottom 0 is projected upward beyond the end C The end C tends to hold the material filled into the measuring receptacle C in check until the gate D has reached about half open position.

Various means may be employed for operating the double gate D, D, as shown for instance in Figs. 1 and 7. The material passing out of the outlet C passes over a short guiding chute F into a receiving receptacle G in the form of a mounting bucket hung on a hoisting rope G and adapted to travel up and down in a shaft or well H. The receiving receptacle G is provided on its bottom with a fork G adapted to straddle a rod I held on a rope or cable J passing over pulleys K, K, K and K arranged in a shaft H, as indicated in Fig. 1. A rod 1 is arranged on the rope or cable J near the pulley K to be engaged. by the top of the receptacle G when the latter is raised to dumping position. One end of the rope or cable J is attached to a pin L held on the upper end of one of the arms D and the other end of the rope or cable J is attached to the pin held on the lower end of one of the arms D \Vhen the receiving receptacle G has descended to receiving position, as shown in full lines in Fig. 1, its fork G engages the rod I and on the further descent of the said receptacle G a traveling motion is given to the rope or cable J so that a pull is exerted on the pin L to swing the gate D into closed position while the gate D swings into open position to allow the measured material in the measuring receptacle C to pass through the outlet G into the receiving receptacle G. After the material has passed from the measuring receptacle G the latter is hoisted and in doing so the top engages the pin 1 whereby a traveling motion is given to the rope or cable J in a reverse direction. A pull is now exerted by the rope or cable J on the pin L to swing the gate D into closed position and the gate D into open position for refilling the measuring receptacle C, as previously explained. The above described operation is repeat-ed on the next descent and ascent of the receiving receptacle G.

By the arrangement shown in Fig. 7 the lower end of one of the arms D is connected by a link N with one end of a lever O fulcrumed at O in the shaft H, and from the said lever 0 depends a rod P provided with a transverse pin P adapted to be engaged by the fork G of the receiving receptacle G at the time the latter moves into lowermost position. From the lever 0 extends upwardly a rope or cable Q, provided with a pin Q adapted to be engaged by the top of the receiving receptacle G at the time the latter moves into uppermost discharging position. The rope or cable Q passes over a pulley R and is provided with a counterweight S to hold the rope or cable Q at all times in taut position.

It will be noticed that when the receiving receptacle G moves into lowermost position a downward swinging motion is given to the lever 0 so that the link N actuates the gates D, D to swing the gate D into closed position and the gate D" into open position. When this takes place the measured material passes from the receptacle G into the receiving receptacle G and the latter is then hoisted for discharging its contents. When the receptacle Gr moves into uppermost position it actuates the pin Q so that the lever O is swung upward to cause the opening of the gate D and closing of the gate D.

The supply chute B is preferably somewhat narrower than the measuring receptacle C (see Fig. t) to prevent spilling of the material as the latter passes from the said chute into the receptacle C.
